The present invention relates to a make-up water valve and to a make-up water connection pipe, and to a structure for coupling same together. The coupling structure is one in which the make-up water valve may be inserted into the make-up water connection pipe to simplify the coupling structure between the make-up water valve and the make-up water connection pipe, and at the same time, a check valve of the make-up water valve may be easily assembled with or disassembled from the make-up water connection pipe to easily perform maintenance and repair processes on the make-up water valve and check valve. For this purpose, the make-up water valve of the present invention includes a valve body in which an inlet and outlet for make-up water are defined, a plate reciprocating so as to open or close a path between the inlet and outlet, a plunger contacting the plate, an elastic unit for elastically supporting the plunger against the plate, and a solenoid valve for vertically operating the plunger when power is applied. The cross-secton of both the inlet and outlet of the valve body has a concentric tube shape. |
